T 0 all whom it may concern:

Be it known that I, NEKOLAI DAHL, merchant, a citizen of the Kingdom of Norway, residing at Fjordgaden 82, city of Trondhj em, Norway, have invented a new and useful Improvement in Box-Fasteners; and I do NEKOLAI DAHL, OF TRONDHJEM, NORWAY.

Specification of Letters Patent.

Application filed. August 25, 1908. Serial No. 450,189.

hereby declare the following to be a full, part, 8, of the cover.

clear, and exact description of the same.

In my United States Patent No. 900084, I

have described a box-fastener adapted especially for closing boxes serving for shipment fastener comprises two elastic levers turnably arranged on opposite sides of the case or box, each lever provided, at its upper part, with an angle piece the upper hook-like portion of which projects over and against the top surface of the cover or over and against the The plate is preferably made nearly cirsurface of a recess in the cover. The said cular, and has an upper portion, 15, carrying the rivet, 3, diametrically opposite the exit fast in closing position, by turning the letension, 16. Partly in order to strengthen ver obliquely to one side. "W hen using the described fastening-device, it is necessary (in portion is brought against the cover to press order to brin the same securely in closing ing, the plate where it wrong position, or the rivet connecting it with the lever being torn off.

My present invention has for its object to provide a box-fastener which does not have device, especially in point of security, is superior to that formerly known.

Into the latter reremovable cover, in combination with a device for holding the cover in place and for permitting removal of the same, said deoverhanging hooked portion, 5, of the fastenvice consisting of a metal plate pivotally secured on one side of the case and provided cess or into both of these recesses, according to the position of the fastening device, the

The removable part, 6, one or more strips, 11, secured thereto, which are formed so as to extend (as shown in Fig. 1) underneath a board of the fixed Now, in order to prevent the necessity of hammering or bending the angle piece, 4, 5, during the fastening or releasing of the device, the lever of my former patent is, according to the present inof herrings and other fish. The said boxvention, replaced by a plate, 12, which, at an end, 16, projecting therefrom, is provided with a raised portion 13, having enlarge ments or edges, 14, which may be struck, or hammered, when the lever or plate is to be turned to either open or to close the device.

Figs. 1 and 3 show the device in position and holding the removable cover part tightly to the box. The swinging of the projection, 16, to the left has caused the hook (4, 5) to be drawn down, as far as possible, into the Fig. 2, showing also a portion of the box and groove 7, and to press upon the removable cover against which the hooked end of the cover-part, 6. To release the cover, it is fastening is gripped; and Fig. 4 is a sectional 1 necessary only to turn the device to the view on the line ll-ll of Fig. 2. position shown in Fig.
